when is it gonna start to smell

my plant is almost 4 weeks old im growing it in a closet wen is gonna start to sell and how bad is it gonna be and its not no exotic

it depends on what kind of weed you got in there and how well you take care of it. and usually a few weeks into flowering.

when should i put my plant into flowerin and its just a good mids seed this is all just an experiment to see if i can do it before i buy a nice seed

you can put it into flower whenever you want. i would do it depending on the space you have. keep in mind it will get 2 or 3 times the size it is when you start to flower.

put it in flower now , it will start to smell really good at about 4-5 weeks in
